HTF Episode Description

Lumpy has Flippy over to watch a swimming competition on T.V. but is caught with his pants down. It’s sink or swim time as Lumpy tries to keep one step ahead of Flippy. Which one of them is going to get caught “underwear”?


"For Max"

The episode starts off with a TV being turned on. On the screen, it shows Cuddles and Giggles about to compete in a swimming race. Flippy sits on a chair as Lumpy brings a piece of cheese and a potato peeler on a plate. Unfortunately, The Mole fires his starting pistol and causes Flippy to flip out and change into Fliqpy. Grabbing the potato peeler, he slices a piece of skin off Lumpy's rump. Upon realizing the danger he is in, Lumpy tries to escape through a window, which Fliqpy closes on him.

Lumpy manages to free himself, but by skinning his lower torso and legs. He pulls his skin, now resembling a pair of pants, out the window. The wound reveals Fliqpy about to finish the job, so he runs away. Seconds later, a butterfly lands on Fliqpy's hand and reverts him back to Flippy.

Meanwhile, Lumpy tries to put his skin back on and stumbles into a laundromat. He throws his skin into a washer, but it shrinks to the appearance of swim briefs. However, Lumpy sees Disco Bear on TV, about to compete at the swim competition, and gets another idea.

Russell, Cro-Marmot, Disco Bear and Lumpy later appear at the swimming pool for the next event. Flippy is seen sitting with the audience, raising a flag. As Lumpy gets ready to dive, he puts on his goggles, and The Mole fires his pistol which startles Flippy again. After a quick dive, Lumpy surfaces to find Flippy flipped out and turned into Fliqpy, with all of the audience massacred (except for Handy whose legs are cut off).

Swimming to the other end of the pool, Lumpy cringes as Fliqpy pounces. However, Fliqpy bounces off Lumpy's "briefs", and onto a flag pole. Impaled, he painfully tries to climb back up to safety. Frantically trying to get Fliqpy down, Lumpy raises down the flag and ends up killing him. As Lumpy salutes, his skin briefs slide down his legs.


"Put your pants on one leg at a time."


  1. Flaky is split in half. (Death not seen)
  2. Nutty is drowned. (Death not seen)
  3. Toothy and Truffles are beheaded. (Deaths not seen)
  4. Giggles is impaled by a stick. (Death not seen)
  5. Sniffles' head is cut in half. (Death not seen)
  6. An elephant and one or more Generic Tree Friends are also killed by Fliqpy. (Deaths not seen)
  7. Fliqpy is impaled on a flag pole and subsequently disemboweled by Lumpy.


  1. Lumpy's skin from the waist down is torn off. 
  2. Handy's feet were cut off.


  • The following is seen when Lumpy surfaces the pool: a car is seen on it's side, the bleachers are set on fire, a tall flag is bent up, and one of the stairs on the bleachers is broken.


  1. Lumpy's antlers change directions, sometimes during continuing shots.
  2. The TV channel is changed in the beginning, but the TV buttons are not visibly touched and no remote is seen.
  3. If Giggles is a competitor, why is she in the audience? (She could have been allowed to join after her race.)
  4. David Winn and Aubrey Ankrum are the only voice actors to have their names written in the credits (in the "Voices" section), despite that voices from characters who are not voiced by any of the mentioned voice actors are heard.
  5. It would not be possible for Flippy to return to normal by seeing a butterfly, considering he once killed a woodpecker. However, the reason could be that he has more power to control himself.
  6. Nutty and Truffles are nowhere to be seen in the audience, but when Lumpy surfaces, Nutty's arm is sticking out of the water and Truffles' severed head can be seen at the poolside. It is possible that one or both of them were inside the car before it crashed.
  7. Lumpy does not stain the pool water when he swims.
  8. Lumpy does not feel pain upon walking despite the skin of his feet also being ripped off.
  9. When Lumpy is shown underwater, Nutty's dead body is nowhere to be seen.
  10. When Handy's legs are cut off, his bones are not visible.
  11. Lumpy spends only half a second underwater, yet Fliqpy manages to kill the audience, an elephant, a Generic Tree Friend, Nutty, and Truffles. On top of this, Flippy also had to flip out, since he was normal before Lumpy was underwater. This may be another sign that Fliqpy kills quite fast.
  12. When Lumpy is about to dive in, Disco Bear's left ear and chest hair are missing (unless the scene took place at an angle).
  13. After Flippy flips out and causes the carnage, Sniffles is briefly seen close to him when he was really at the far side of the bench. However, it is possible that Flippy put Sniffles close to him before killing him.
  14. Sniffles is seen 'floating' when he is shown (or he was sitting down, but it looked as if he was floating).
  15. It is odd that Cro-Marmot participates in the swimming contest, considering several characters are aware of what his block of ice can do in the water.
  16. When Fliqpy gets impaled by the flag pole and slides down, a bit of his hand is missing.
  17. Disco Bear can be seen in the swimming competition in this episode, despite his inability to swim in See What Develops.
  18. Because Lumpy's veins were exposed, he should have felt a sharp pain when entering the water.
